Public Instance Methods

connect(family = Socket::AF_UNSPEC, addrinfo_flags = 0) click to toggle source

Connects to this Reply. If target and port are missing, DNSSD.resolve is automatically called.

family can be used to select a particular address family (IPv6 vs IPv4).

addrinfo_flags are passed to DNSSD::Service#getaddrinfo as flags.

# File lib/dnssd/reply/resolve.rb, line 58
def connect(family = Socket::AF_UNSPEC, addrinfo_flags = 0)
  addrinfo_protocol = case family
                      when Socket::AF_INET   then DNSSD::Service::IPv4
                      when Socket::AF_INET6  then DNSSD::Service::IPv6
                      when Socket::AF_UNSPEC then 0
                      else raise ArgumentError, "invalid family #{family}"
                      end

  service = DNSSD::Service.new

  service.getaddrinfo target, addrinfo_protocol, addrinfo_flags,
